Our findings elucidate pivotal insights into their antibacterial, antioxidant, and anti-inflammatory effects. A comprehensive series of experiments involving microbiological, biochemical, and cellular methods was conducted to demonstrate that the bioactivities of these compounds are significantly influenced by their concentrations. It is noteworthy that hesperetin exhibits concentration-dependent antibacterial activity against a broad spectrum of bacteria, including <i><i>Escherichia coli</i></i>, <i>Staphylococcus aureus</i>, and <i>Streptococcus mutans</i>, while naringenin shows varying degrees of inhibition depending on the bacterial species. Additionally, hesperetin demonstrates superior antioxidant capacity compared to naringenin, as evidenced by its higher DPPH radical scavenging activity. Moreover, both compounds have been observed to promote the proliferation of RAW 264.7 cells at low concentrations, yet exhibit inhibitory effects at higher doses. It is noteworthy that both hesperetin and naringenin effectively suppress the expression of inflammation-related genes, including TNF-α, IL-1β, and iNOS, in RAW 264.7 macrophages. This highlights their potential as anti-inflammatory agents. These outcomes provide valuable information for optimizing the use of hesperetin and naringenin in the pharmaceutical and food industries, contributing to the advancement of flavonoid research and offering a foundation for future applications.</p>","PeriodicalId":72048,"journal":{"name":"ACS food science & technology","volume":"5 2","pages":"492–501 492–501"},"PeriodicalIF":2.6,"publicationDate":"2025-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143452502","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, whether covalent Se-grafting of YP could lead to changed antioxidant and hypoglycemic activities remains unknown. YPs were thus separated from fresh Chinese yam tubers using water extraction and enzymatic treatment and then chemically selenized to yield two products, namely, YPSe-I and YPSe-II. These products acquired covalent Se-grafting in the form of selenite and had different Se contents (0.795 and 1.48 versus 0.035 g/kg) or selenization extents. The results obtained from the determination of antioxidant capacity indicated that the two Se-grafted products possessed a higher antioxidant activity compared to YP because they were more effective in scavenging both OH and ABTS radicals or reducing Fe<sup>3+</sup> to Fe<sup>2+</sup>. Meanwhile, the two Se-grafted products, especially YPSe-II, had a higher capacity than YP to inhibit the activities of two digestive enzymes, namely, α-amylase and α-glucosidase. The results derived from cell experiments indicated that YP, YPSe-I, and YPSe-II were not cytotoxic to the normal BRL-3A liver cells and established insulin-resistant BRL-3A cells. However, YPSe-I and particularly YPSe-II exhibited a hypoglycemic effect in the model cells that was higher than that of YP, resulting in increased glucose consumption and enhanced oxidase activities in superoxide dismutase, catalase, and glutathione peroxidase. Data comparison results also manifested that YPSe-II consistently demonstrated higher antioxidant and hypoglycemic activities than YPSe-I. It was thus concluded that the covalent Se-grafting and high selenization extent endowed the Se-grafted YP products with enhanced beneficial functions, such as antioxidant and hypoglycemic effect. Meanwhile, this covalent Se-grafting could potentially serve as a suitable chemical approach to modify the two beneficial functions of natural polysaccharides.</p>","PeriodicalId":72048,"journal":{"name":"ACS food science & technology","volume":"5 2","pages":"734–742 734–742"},"PeriodicalIF":2.6,"publicationDate":"2025-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143452501","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
